Magmatic origin of giant ‘Kiruna-type’ apatite-iron-oxide ores in Central Sweden
Iron is the most important metal for modern industry and Sweden is by far the largest iron-producer in Europe, yet the genesis of Sweden's main iron-source, the 'Kiruna-type' apatite-iron-oxide ores, remains enigmatic. We show that magnetites from the largest central Swedish 'Kiruna-type' deposit at Grängesberg have δ(18)O values between -0.4 and +3.7‰, while the 1.90-1.88 Ga meta-volcanic host...
متن کاملبررسی زمین‌شیمی و کانه‌زایی آهن و آپاتیت برای شناخت عناصر خاکی نادر در کانسار گزستان منطقه بافق (استان یزد)
Gazestan deposit is located about 185 km of Yazd, in the Bafgh – Posht e Badam Metallogenic belt, consists of Infracambrian carbonate, shale, tuff, sandstone and volcanic rocks. Acid to basic green rocks (rhyolite, dacite and basalt) are host for iron and phosphate mineralization. The alteration process is more intence in the volcanic rocks including, actinolite, chloritization, silicification ...
متن کاملPetrology and Geochemistry of Early Cambrian Volcanic Rocks Hosting the Kiruna-type Iron Ore in Anomaly 10 of Sechahun, Central Iran
Early Cambrian volcanic rocks of the Posht-e Badam tectonic block in Central Iran which is hydrothermally altered to green color rocks, hosts the Kiruna-type Iron Oxide-Apatite (IOA) mineralization in Anomaly 10 of Sechahun deposit. Geochemically, these volcanic rocks are classified as high-potassium calc-alkaline and mainly consist of rhyolite and trachyandesite. These rocks are important for ...
متن کاملmineralogical and geochemical studies on apatites and phosphate host rocks of esfordi deposit, yazd province, to determine the origin and geological setting of the apatite
introduction iron-apatite ore deposits well known as kiruna iron type formed in association with calc-alkaline volcanism from proterozoic to tertiary (hitzman et al., 1992). liquid immiscibility in an igneous system was proposed to explain the formation of the iron oxides accompanying apatite in mineralized zones (förster and jafarzadeh, 1994; daliran, 1999). the mode of ore formation however, ...
متن کاملMineral chemistry of magnetite and fluid inclusions studies in the Kuh-Baba iron deposit, south of Hashtroud, NW Iran
The Kuh-Baba iron ore deposit is located about 70 km south of Hashtroud, East-Azarbaidjan Province, NW Iran. The deposit is genetically affiliated with intrusive bodies of gabbroic to dioritic composition. The principal host rocks for the Fe mineralization include units of gabbro-norite and pyroxene hornblende gabbro-norite. The widespread alteration zones which are accompanied with Fe-minerali...
